All the WebP images I’ve made available here are losslessly compressed. You can verify this yourself by running
strings file.webp | grep VP8
and verifying that the string “VP8L” is in the file. You can also just look at the file in a text editor like Notepad if that’s a more familiar tool.
(A mere “VP8” means it’s lossily compressed, “VP8L” means losslessly compressed, and “VP8X” means it supports alpha channels, animation, and metadata. A WebP file can be both losslessly compressed and have extended stuff.)
Of course, you’re going to have to trust me that I haven’t made those lossless WebP files from a JPEG from a PNG from a PNG from a JPEG from a lossy WebP from a PNG from a JPEG.
